Application filed June 15; 1911; Serial No. 633 4041 being formed; from similar cross strips 16 of a length greater than the distance between the door posts, and having their, edges beveled as at 17so as to give a grain- The strips of eachflsection are secured to each other by hinge members 18 ofiangle iron cross section having portions, permanentlysecured to the back ofthe strips and the opposite portions extending. at right angles therefrom and connected together by.

pivot. p ins .19.' The door posts have their inner corners rabb'eted' away at 20, and 1 plates 21 are firmly fastened to the inner sides-of the. door and'formwithihe rab: "beted' door posts vertically directed channels 22 which receive the ends of'the door sections. thatthe members 18 are. arrangedso that At this point it is to be. noticed theinrearwardly directedportions, or those, extending at right. angles from the door, appear directly to.the sides of; the plates 21'. This'prevents the door from.end-;play and insures also a grain tightjointbetw'een therposts and the door 23and2h areshafts carried by suitable bearings 25 interposed between the floor beams 11' and l2,fl which shafts carry bevel Wheels 26 and 27, respectively, meshingwith further bevel wheels 28 and 29carriedby short counter. shafts 3O and 31mounted in the beams.v

32 are ratchet ;.whee1s fikedon the outer ends of the shafts, and 33"are pivoted rat-chets engageable with the ratchehwheels.

34 are levers releasably secured. to the shafts. 35are loose pulleys located in housings 36' appearingonthe roofgof the, carmore or less directly above the door posts.

37 and B7; 38,"and38"are straps firmly. riveted tothe lower cornersof the door sec- 95 tion, respectively.

39' and 40 are cords. or cables passing from the shaft 23up wardly within the. channels.

22 through the roof'and over a pair ofpul: leys .35 within thehousings 36; whence they are turned downwardly. at the opposite or outer sides of the door posts, through th'e car floor 41 and-back to the shafts where they are secured, The cords are fastened also to the straps 37, and 37 42 and43 are, further cords or cables fastened to the shaft 2 1' andpassifng upwardly within the. channels andthroughthe roof'over the second pair of pulleys 35 where they return downwardly at theouter side of the posts and pass through the floor to the shaft (2%) where they are secured. The cords L2 and 43 are fastened permanently to the straps 36 and 38 respectively. Accordingly'the door sections can be raised or lowered at will by turning the shafts with the cranks.

In order that the door sections can be stacked or housed within the roof of the car when not in use, I have provided the following parts which are carried by the roof beams: 44 and 45 are supporting beams firmly fastened to a pair of the roof beams 7 and passing across the central portion of the car. The bars are spaced apart so as to allow one of the door sections to pass between them, while theupper bar is positioned sufficiently far beneath the car roof to allow the other above its section to pass.

,- 46 and 47 are switch bars pivotally secured by pins 48 and 49'to the aforesaid pair of beams 7 and having their lower ends tapered to an edge and resting on shoulders 50 formed in the upper ends of the plates 21 by cutting away portions 50' of the upper inner corners of the plates.

Assuming the switch bars in the position shown'in Fig. 2 of the drawings, and that the upper section of the door is raised by the turning of the shaft 23 in a proper direction, the door section will pass up wardly within the channels until its upper edge engages the angularly disposed face 4 of the lintel by which it is swung inwardly and falls on the upper switch bar 47. As

the cords continue to draw the lower edge of the door section upwardly the advancing edge thereof passes between the roof of the car and the supporting bars 4-4 and when it comes to its final position the lower end of a the switch bar is swung upwardly to the dotted position (see Fig. 2). This operation will be readily understood when one remembers that the vweight of the advancing end of the door is carried by the upper ends of the switch bars at a time when the lower end is held free of the lower ends of the switch bars by the cables. When thesec- 0nd section of the door is raised by turning the shaft 24 its advancing edge is deflected by the switch bars 47 on to the switch bars 46, which bars take the position shown n F 1g. 2 when the section is wholly up. It is pointed out that the door sections are released from the channels by passing through the openings 50 formed by cutting cables with the other of the door sections,

and supporting bars secured to t-heroof' 1 beams for receiving the doors after they are passed over the switch bars, as and for the purpose specified.
